Email campaign with malware: Javascript downloaders instead of executables as attachments

Several types of emails are being sent with a ZIP attachment containing a single file with this mask: <number>.doc.js.

The copy of the invoice is attached to this email.

Yours faithfully,

Well, since now I uploaded it for the first time, all of them will, fortunately, detect it soon.
